Abstract
Objectives
Optimal use of surgery first (SF) vs neoadjuvant therapy (NAT) for localized pancreatic ductal adenocarcinoma (PDAC) is still unclear. There is concern that NAT may result in worsened post-operative outcomes. Our study objectives were to show the impact of NAT on post-operative morbidity and mortality.
Methods
All patients undergoing resection for PDAC between 1/1/2010 and 12/31/2020 were reviewed and those who underwent pancreaticoduodenectomy (PD) were included. Demographics, perioperative details, and pathology details were gathered. Data pertaining to 90-day complications were obtained and graded according to international consensus guidelines. Those undergoing SF were compared to those who had NAT. Categorical variables were compared by Fisher’s exact test and continuous variables by Student’s t-test.
Results
Two hundred and forty-one subjects who underwent PD for PDAC were included in this review. There was no significant difference in the rate of major morbidity between subjects who received NAT vs SF (19.4 vs 20.3%, P = 1.0). Similarly, there were no significant differences in the rates of mortality (3.1 vs 4.2%, P = .742), post-operative pancreatic fistula (8.2 vs 10.5%, P = .658), or post-pancreatectomy hemorrhage (7.1 vs 7.7%, P = 1.0), respectively.
Conclusion
Post-operative outcomes are not worsened by the use of the NAT approach prior to PD for PDAC. Further investigation is needed to reveal which patient subgroups may benefit from the use of NAT, especially regarding survival.
